I'm trying to create a column chart (specifically 100% stacked column chart). The labels along my X-axis are sample names, however when I create a chart Power BI creates what appears to be a random order and doesn't follow the order of the data table. The sample names contain both numbers and letters so are inputted as text values, and selecting "Sort by column" doesn't help. If I remove the letters, leaving just numbers, it arranges it numerically (which is fine) but leaves massive gaps along the number line because the nature of the samples means they're not consecutive numbers.
I've also tried creating a column of numbers and using "Sort by column" to sort the sample name column by the number...but no luck.
Suggestions?
